In the study of MIMO uplink 8-port transmission enhancement, the design of fully coherent codebook, partially coherent codebook, incoherent codebook, Transmit Precoding Matrix Indicator (TPMI) design, and full power transmission are discussed. Optionally, the number of antenna port groups of the terminal is defined, that is, the number of antenna port groups of the terminal is defined as Ng, and the antennas in each antenna port group are fully coherently transmitted, and the antennas between different antenna port groups are incoherently transmitted. When the terminal is a fully coherent terminal, Ng = 1; when the terminal is a partially coherent terminal, Ng = 2 or 4; when the terminal is an incoherent terminal, Ng = 8. For the 8-port fully coherent codebook, the 8-port R15 downlink Type I codebook is used, and the oversampling coefficient is set to 1. For the partially coherent codebook with Ng = 2, the design is based on the R15 uplink 4-port codebook. For the partially coherent codebook with Ng = 4, the design is based on the R15 uplink 2-port codebook. For the non-coherent codebook, all antenna selection vectors or antenna selection matrices are used.

However, for some 8-port codewords, full power transmission cannot be achieved due to the limitation of the physical uplink shared channel (PUSCH) power control rules. Optionally, in the PUSCH power control rules, its transmission power needs to be multiplied by the power scaling factor, which is defined as the number of antenna ports for non-zero PUSCH transmissions divided by the total number of configured antenna ports. For example, when the 4-port codeword is When the 4-port codeword is When , the parameter is 4/4=1, that is, full power transmission can be achieved. Therefore, when the number of uplink transmission ports is 8, the full coherent codebook can achieve full power transmission, when the number of layers of the partially coherent codebook Ng=2 is 1, full power transmission cannot be achieved, when the number of layers of the partially coherent codebook Ng=4 is 1 to 3, full power transmission cannot be achieved, and when the number of layers of the incoherent codebook is 1 to 7, full power transmission cannot be achieved.

In the discussion of R16 uplink 2-port and 4-port full-power transmission, multiple full-power transmission modes are defined to achieve full-power transmission. First, according to the different power amplifier (PA) architectures of the terminal, for the terminal of power class 3, the full power, maximum power or rated power (full rated) of the amplifier is 23dBm, so three different terminal capabilities are defined. The following takes the 2-port terminal as an example.

Terminal Capability 1: The RF chain corresponding to each port is configured with a PA with maximum rated power output, for example [23 23]dBm

Terminal capability 2: The RF chain corresponding to each port is not configured with a PA with maximum rated power output, for example [20 20]dBm

Terminal capability 3: The RF chain corresponding to some ports is configured with a PA with maximum rated power output, for example [23 20]dBm

In response to the above three terminal capabilities, R16 proposes three full-power transmission modes, namely Mode 0, Mode 1 and Mode 2 below.

Mode 0: In Mode 0, the PUSCH power scaling factor is fixed to 1, corresponding to terminal capability 1. Since each PA can transmit at full power, even non-coherent codewords can be transmitted at full power. For example, for codeword Among them, the part of the coherent codeword is the coefficient of the codeword. , full power can be transmitted only through the first PA.

Mode 1: In Mode 1, the codeword that can support full power transmission is introduced on the basis of the original codebook subset restriction, so as to achieve For example, for a 4-port 2-layer non-coherent codebook, a 4-port 2-layer partially coherent codeword is introduced.

Mode 2: In Mode 2, full-power transmission can be achieved through two methods. In method 1, full-power transmission of a single port can be achieved through port virtualization. The implementation of port virtualization involves the modification of the sounding reference signal (SRS) resource configuration method and the modification of the PUSCH power control rule. For example, for PA = [20 20 17 17] dBm (i.e., the first port, the second port, the third port, and the fourth port correspond to 20, 20, 17, and 17 dBm, respectively), the base station configures 2-port SRS resources, and the terminal can obtain [23 20] dBm through SRS port virtualization, i.e., the first two ports are virtualized into one port. At this time, two 20 dBm can be virtualized to obtain 23 dBm, and the third and fourth ports are virtualized into one port. At this time, two 17 dBm can be virtualized to obtain 20 dBm. In this way, the codeword is used. In method 2, the terminal reports a TPMI group that can support full-power transmission according to the PA architecture. For example, for PA = [20 20 20 17] dBm, TPMI group G3 can be reported. Table 1 is a schematic table of TPMI group G3, where TPMI group G3 can enable the terminal to achieve full-power transmission under PA = [20 20 20 17] dBm.

However, in the above-mentioned Mode 2 method 2, it is not yet clear how the terminal reports the TPMI supporting full-power transmission to the network device.

FIG2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to a communication method, which is used in a communication system 100, and the method includes:

Step 2101: The terminal sends a first signaling.

Optionally, the terminal can be configured to transmit at full power based on method 2 in Mode 2 above.

Optionally, in some embodiments, the first signaling can be used to indicate at least one first TPMI, or the first signaling can be used to indicate at least one first TPMI group, wherein a TPMI group can include at least two TPMIs, and different TPMIs in the same TPMI group correspond to the same number of activated antenna ports. Optionally, the first TPMI and the first TPMI group can be used to enable the terminal to send uplink channels and/or uplink signals at full power.

Optionally, the number of activated antenna ports can be understood as the number of antenna ports corresponding to non-zero elements in the TPMI. Optionally, each row of elements in the TPMI corresponds to an antenna port, and when the element corresponding to a certain antenna port in the TPMI is a non-zero value, it means that the antenna port is activated. Optionally, when the activated antenna port is connected to a PA that can achieve full-power transmission, the terminal can achieve full-power transmission.

Optionally, in some embodiments, the number of antenna ports activated in the first TPMI or the number of antenna ports activated in the TPMI included in the first TPMI group is a first value, and the first value is greater than or equal to the number of PAs required for the terminal to achieve full-power transmission; optionally, the number of PAs required for the terminal to achieve full-power transmission can be: 1 23dBm PA, 2 20dBm PAs, 4 17dBm PAs, and 6 15.3dBm PAs. Optionally, when the number of PAs required to achieve full-power transmission is one 23dBm PA, such as when the PA structure of the terminal is: PA = [14 14 14 14 14 14 14 23] dBm, the number of antenna ports activated in the first TPMI or the number of antenna ports activated in the TPMI included in the first TPMI group should be greater than or equal to 1. At this time, it can be ensured that the one 23dBm PA can be connected to the number of activated antenna ports to achieve full-power transmission; when the number of PAs required to achieve full-power transmission is two 20dBm PAs, such as when the PA structure of the terminal is: PA = [14 14 14 14 14 14 20 20]dBm, the number of antenna ports activated in the first TPMI or the number of antenna ports activated in the TPMI included in the first TPMI group should be greater than or equal to 2. At this time, it can be ensured that the two 20dBm PAs can be respectively connected to the number of activated antenna ports to achieve full-power transmission; when the number of PAs required to achieve full-power transmission is 4 17dBm PAs, such as: when the PA structure of the terminal is: PA = [17 17 17 17 14 14 14 14]dBm, the number of antenna ports activated in the first TPMI or the number of antenna ports activated in the TPMI included in the first TPMI group should be greater than or equal to 4. At this time, it can be ensured that the 4 20dBm PAs They can be respectively connected to the number of activated antenna ports to achieve full-power transmission; when the number of PAs required to achieve full-power transmission is 6 17dBm PAs, such as: when the PA structure of the terminal is: PA = [14 14 15.3 15.3 15.3 15.3 15.3 15.3], the number of antenna ports activated in the first TPMI or the number of antenna ports activated in the TPMI included in the first TPMI group should be greater than or equal to 6. At this time, it can be ensured that the 6 20dBm PAs can be respectively connected to the number of activated antenna ports to achieve full-power transmission.

Optionally, in some embodiments, the terminal may include 8 antenna ports. Optionally, when the terminal is an 8-port partially coherent terminal or an 8-port fully coherent terminal, the first signaling may be used to indicate at least one of the following: a bitmap of a 2-port TPMI, a 4-port incoherent TPMI, a 4-port incoherent TPMI group, a 4-port partially coherent TPMI, a 4-port partially coherent TPMI group, an 8-port incoherent TPMI, an 8-port incoherent TPMI group, an 8-port partially coherent TPMI, and an 8-port partially coherent TPMI group. Optionally, in some embodiments, when the terminal is an 8-port incoherent terminal, the first signaling may be used to indicate at least one of the following: a bitmap of a 2-port TPMI, a 4-port incoherent TPMI, a 4-port incoherent TPMI group, an 8-port incoherent TPMI, and an 8-port incoherent TPMI group.

Optionally, the bit map of the 2-port TPMI, the 4-port incoherent TPMI, the 4-port incoherent TPMI group, the 4-port partially coherent TPMI, and the 4-port partially coherent TPMI group are introduced below.

Optionally, when the first signaling indicates a bit map of a 2-port TPMI, it indicates that the antenna ports of the terminal are currently virtualized, wherein 8 antenna ports are virtualized into 2 ports, and every 4 antenna ports are virtualized into one port. The 2 ports obtained after virtualization correspond to the 2-port TPMI. At this time, the 4 antenna ports of the terminal will simultaneously correspond to a codeword in the 2-port TPMI; Optionally, when the first signaling indicates a 4-port TPMI (such as a 4-port incoherent TPMI, a 4-port incoherent TPMI group, a 4-port partially coherent TPMI, a 4-port partially coherent TPMI group, etc.), it indicates that the antenna ports of the terminal are currently virtualized, wherein 8 antenna ports are virtualized into 4 ports, and every 2 antenna ports are virtualized into one port. The 4 ports obtained after virtualization correspond to the 4-port TPMI. At this time, the 2 antenna ports of the terminal will simultaneously correspond to a codeword in the 4-port TPMI.

Optionally, in some embodiments, the above 8-port TPMI or 8-port TPMI group is introduced below. Optionally, when the antenna port groups of the terminal are different, the 8-port TPMI or 8-port TPMI group indicated by the first signaling is also different.

Optionally, when the number of antenna port groups of the terminal is 8, at this time, each antenna port is divided into 1 group, the first TPMI or the TPMI in the first TPMI group can be an 8-port non-coherent TPMI, and the number of transmission layers corresponding to the first TPMI or the TPMI in the first TPMI group is 1 layer, 2 layers, 3 layers, 4 layers, 5 layers, 6 layers, or 7 layers, and the number of activated antenna ports corresponding to each transmission layer of the first TPMI or the TPMI in the first TPMI group is 1.

For example, when the number of antenna port groups of the terminal is 8 (that is, each antenna port group includes 1 antenna port), if the PA structure of the terminal is: PA = [14 14 14 14 14 14 14 23] dBm, 1 PA can be transmitted at full power. At this time, the first TPMI or the TPMI in the first TPMI group can be G0 in the following Table 1; if the PA structure of the terminal is: PA = [14 14 14 14 14 14 20 20] dBm, 2 PAs can transmit at full power. In this case, the first TPMI or the TPMI in the first TPMI group can be G1 in Table 1. If the PA structure of the terminal is: PA = [20 20 20 20 20 20 20 20] dBm, any two PAs can transmit at full power. In this case, the first TPMI or the TPMI in the first TPMI group can be G2 in Table 1. If the PA structure of the terminal is: PA = [17 17 17 17 14 14 14 14] dBm, 4 PAs can transmit at full power, at this time, the first TPMI or the TPMI in the first TPMI group can be G3 in Table 1. If the PA structure of the terminal is: PA = [17 17 17 17 17 17 17 17] dBm, any 4 PAs can transmit at full power, at this time, the first TPMI or the TPMI in the first TPMI group can be G4 in Table 1; if the PA structure of the terminal is: PA = [14 14 15.3 15.3 15. 3 15.3 15.3 15.3]dBm, 6 PAs can transmit at full power. In this case, the first TPMI or the TPMI in the first TPMI group can be G5 in Table 1; if the PA structure of the terminal is: PA＝[15.3 15.3 15.3 15.3 15.3 15.3 15.3]dBm, any 6 PAs can transmit at full power. In this case, the first TPMI or the TPMI in the first TPMI group can be G6 in Table 1.

Table 1

Optionally, in some embodiments, the number of activated antenna ports in the same TPMI group is the same. For example, the TPMI group G2 shown in Table 1 above For example, the TPMI group Each TPMI in the system should be a 2-layer transport layer, and each layer should be equally divided. Each of these corresponds to an activated antenna port. Can include Similarly, the TPMI group in G2 shown in Table 1 above Each TPMI in the group should be a 3-layer transmission layer, and each layer corresponds to an activated antenna port.

Optionally, in some embodiments, when the element value corresponding to a certain antenna port in a certain transmission layer is a non-zero value, it can be understood that the antenna port is mapped to the transmission layer. For example, for the TPMI group {[1 1 0 0 11 0 0] ^T }, the first, second, fifth, and sixth antenna port groups are mapped to the first layer. Then the TPMI group {[1 1 0 0 11 0 0] ^T } needs to include all codewords having the same first mapping mode as [1 1 0 0 11 0 0] ^T.
